In order to evaluate the style shifting in Obama’s speech, the paper will use four speeches of President Obama between January 2008 and September 2011. The speeches which will be evaluated are: Congressional Black Caucus Foundation which will be referred as CBC; speech at Hampton University which will be referred as Hampton University; King’s Church speech and A More Perfect Union. The speeches chosen for the analysis cover the same topic therefore to make sure that number of external factor affecting the speech are minimized while making “audience” as the only governing factor of the speeches. The number of speeches for analysis is kept four as to keep the limited scope of the paper in mind. As the purpose of the paper is to identify the possible linguistic features used by President Obama therefore there are terms used throughout the paper: “AAVE” which denotes to the ethnolect called African America Vernacular English and “GAm which denotes to General (standard) English” which is non-ethically marked variant of American English. (Detert, Rasmussen and Kristensen, p.7) The first step in to start the analysis of the fours speeches to find a result for the hypothesis. This includes analyzing and marking the speech for the phonetic variables which can reveal variables that can be identified as indexical of African American Vernacular English. For the purpose, a computer software known as ELAN is used. ELAN is sound processing software. It helps in marking utterances in a speech and annotating the utterances with different values. However the system is not able to detect the phonetic differences in the speech. Therefore the phonetic difference will be evaluated by the listeners. (Detert, Rasmussen and Kristensen, p.7) The ELAN software has been use to mark and annotate all the variables in the question (see Appendix A). Each variable has been given a value. The variables have also been marked within the categories i.e. “General American English” or “African America Vernacular English”. For example, if there is an annotation with an (ING) variable in the speech, the categorical annotation marks the annotation as>
